Combining symmetry breaking and restoration with configuration interaction: a highly accurate many-body scheme applied to the pairing Hamiltonian
J. Ripoche, D. Lacroix, D. Gambacurta +2
Background: Ab initio many-body methods have been developed over the past ten years to address mid-mass nuclei... As progress in the design of inter-nucleon interactions is made, f…
Chiral potential renormalized in harmonic-oscillator space
C. -J. Yang
We renormalize the chiral effective field theory (EFT) potential in harmonic-oscillator (HO) model space. The low energy constants (LECs) are utilized to absorb not just the ultra-…
From resonantly interacting fermions with effective range to neutron matter
Denis Lacroix
A density functional theory is proposed for strongly interacting fermions with arbitrary large negative scattering length. The functional has only two parameters that are directly…
Can Ab Initio Theory Explain the Phenomenon of Parity Inversion in Be?
Angelo Calci, Petr Navrátil, Robert Roth +3
The weakly bound exotic Be nucleus, famous for its ground-state parity inversion and distinct n+ Be halo structure, is investigated from first principles using ch…
Spin-orbit interaction in relativistic nuclear structure models
J. -P. Ebran, A. Mutschler, E. Khan +1
Relativistic self-consistent mean-field (SCMF) models naturally account for the coupling of the nucleon spin to its orbital motion, whereas non-relativistic SCMF methods necessitat…
